To all whom it may concern.' f

Be it known that I, THOMAS L. TITUS, a citizen of the United States, residing at Omaha,in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements Y in Fluid-Pressure Valves, of which the following is a speciiication.

This invention relates to an improvement in yfluid pressure valves of the class employing an oil-resistance chamber for a control ofthe main valve, and has for its object broadly, to provide a valve which may be' conveniently and economicallyV manufactured, will consist of parts which may be readily assembled or detached, will be durable in wear, and which may beadjusted for use inconnection with la fluid having various degrees of pressure.

The invention consists of the novel construction, combination and arrangement of parts as described herein and claimed, and as illustrated in the accompanying drawings, wherein,-d

Figure 1 is a view of the valve in longi-- tudinal section, the main valve being disposed on its seat.V Fig. 2 is a bottom plan view of the main valve. Fig. 3 isaview of the valve partly in section, the main valve being open.

While the valve may have various uses it is particularly well adapted for use as a flush valve, and consists, in part, of `an upright casing 5 having an intake port `6, a discharge port 7, and a partition 8 between said ports which is provided. with `a valveseat 9 for a main valve 10 and a valve t seat 411 for a relief valve 12, whereby a chamber 13 is provided on the pressure means tending to prevent vibration and.

objectionable noise usually attending the operation of valves,and means for confining the oil within the oil chamber.

The valve 10 is formed as `a cylindricalreceptacle and is provided, traneversely,l with an endless flange 15 of uniform width,

said flange preferably being v.disposed between the endsV of the v alve. Numeral 116 indicates a sleeve which is stationary with the top of the casing and which traverses the main valve seat 9 at substantially its center, its inner end, within the valve-10, being Vprovided with an annular' valve seat'17.

Numeral 18 indicates a tubular guidedisf y posed with thev center of its` bore inline withV the center'of the main valve seat, said.

guide being a part of the bottom 'screw plate 19 of-the casing and` projecting in* wardly of the chamber 13." Thev lower end of the valve 10 is formed by use of an in-v verted screw-cap 20 providedV with a depending threaded lcollar 21 formed with opposed facets a as best shown in Fig. 2, so

that by using a wrench, it maybe suitably secured :to the bottom of the vvalvefor compressing the packing 22 toy prevent water `from entering the valve chamber.; Theinverted screw-cap 20 is provided, to project bel-ow its bottom, with a cylindrical 'eXtension 23- constantly engaging inthe tubu l'ar guide, V'its longitudinal yaxis ltherefore being maintained .in1 line withVV the longitudinal aXis of the valve 10; and 'it lis provided with numerous grooves l24 formed longitudinally therein which eXtend its entire length. Numeral 25` indicates an auxiliary passageway communicating `With thep'ressure side of the valve yand also communicating with the discharge port 7, subject to thecontrol ofthe valve 12.

Disposed in, the sleeve 16 is a valve-stern; 26 'having a length suliicient to project wi-th-` in the cylindrical extension 23; and mounted,

on the stem is `a retarding-valve 27, said valve Vbeing adapted to VVhave a slidable movement on the stem subject to the resistance of a spring 28` carried by the valve stem, said spring having suiiicient force to Y support the weightfof the valve 27 and also to maintain it, normally, in Vengagement with the lower end of thealining cylinder' or boss 29 of the stem, .said boss b'eingdis-l posed within and having apart projectingv belowthe end ofthe sleeve.`

As thus described, when the valve 10 is reciprocated on 'its stem there will' be no friction except the limited degree caused by the packing-fnac so ana-fthe projection y31 of said valve 10 upon the sleeve 16, and

the contact of the inner wall of the valve 10 with the stationary valve seat 17.

l'Vhenthe release valve is opened by use or' the handle 32, the valve 10 will slide substantially to the position shown in Fig. 3, the oil passing the valve-seat 17 through the annular way 33 and apertures Z), the spring permitting the way 33 to be materially enlarged, and the yextension 23 moving downwardly within the tubular guide 181, the water passing outwardly of the latter into chamber 13 through the grooves 24, the valve 10 being maintained in line with the center ofthe valve seat 9, and the flange 15 being prevented from engaging the walls of the casing, this operation :being practically free from vibra-tion or objectionable noise which is often caused by contact of metallicY parts. Y

Since the pressure ofV water is not uniform in all localities or upon different floors of a building, astop-member 34 is provided, consisting of a sleeve which is threaded upon the tubular guide 18; and this may be rotated-ferite adjustments for controlling the distance to which the valve 10 may move from its seat, and therefore controlling the volume of water which 4may pass the valve seat 9. y

It is-understood top be an advantage, of course, to maintain the annular flange 15 closely adjacent to the walls of 'the kcasing` andthe fact that therel will be no actual contact or wear of these parts is a feature of importance relating to durability.

The parts mentioned for a control of the valve 10 are of equal importance when it Amoves to its seat, the movenient'of the oil from the lower-to the upper side of the valve 27 operating to retard said movement.' Il' it is desired to permit the valve 10 to move more quickly to its scat 9, the valvestem 26 may Vbe adjusted longitudinally, since .its head is' threaded in the bushing 36 of the dome 37. If the water pressure is of limited degree, the space between the valve 2T and its seat-.17 may be decreased, by the above adjustment, so that the flushing will conti-nue ffor, comparatively, a longer period. Y

In the present instance, air is admitted to the chamber C of the valve 10 by means of an aperture 38 formed in the sleeve 1-6 above the oil in the chamber, the slot y39 formed in the head 35 of' the stem, and the aperture 40 formed in the removable plug 41 of the dome., the diameter of the stem 26 above the boss, being lessthan the bore of the sleeve, this ingress and egress of air being of advantage and quite ynecessary .to permit a 'Y suitable movement of the valve 1;() upon the sleeve l16.. and to prevent a movement of the oil, ontw ardlv `ol thechamber Cwhichotherd wise .would be occasioned by suction,lv Y

Itwill be understood that, in order to un? seat the main valve 10, the volume or' water which passes the valve 12 must be greater than the volume which passes the annular area CZ from the intake (i to the auxiliary passageway. 25, the latter having a su'licient length soV that its intake e will be disposed near the bottom or' the casing or at least below kthe flange 15, and according to this construction the annular area may be increased i desired, the bore of the passageway being also increased. This feature will be appreciated since all grinding or milling of the inner walls of the casing or flange 15, which adds to the cost of manufacture, may be `dispensed with.
